Ghost Of Highbury:
i am extremely curious to know how did u find out the cross-sectional area of the wire..(it is so thin!)

ohk,,

plz reply with the values u took

for

length of the wire - ?
  and

cross-section area of the silver wire - ?

------------------

also the voltage u used .

I made up the values for cross sectional area and length.... ;D

If u need to change around any of the values voltage, area or length to make it more logical then please do so.

My teacher didnt give us any values nor did we do an actual experiment, yet im supposed to do the project. So i made the values up....

hope ur estimation for the area is close..

and yea...dont make up values for length...its not cumbersome to measure it with a meter rule...

yea...so what values did u take for the current value u posted recently i.e 15094339.62

holtadit:
the ones i posted in the first post.... once again none of these values have been tried out experimentally so please modify if required

astarmathsandphysics:
Definitely wrong. Did you change to metres
